Torque converter Trouble

Thanks i will try that to day and see i have done everything else I have twisted and turned to i thought my arms were goin to fall off.Never have worked with a 904 alway's been a 727
I tried that and it likes about an inch going down i even tried 3 different TC and they all was doin the same thing i don't know what wrong with it , Do you think it something in the transmission i just had it rebuilt and the guy that done it has been building trans. for me over 40yrs. this is the first for me
